Durability – Whether you’re going on a mission, hiking, exploring a new country, or just carrying your books and laptop to class, a sturdy, well-made backpack is useful.
Freedom of movement – If you have to carry your backpack for long periods of time, the straps and padding should be as comfortable as possible. Having the wrong backpack can make even the most exciting trip boring.
Various compartments – Laptops, books, clothes and accessories… finding them in a bag with no way to compartmentalize your gear is really annoying. A well-designed backpack does not have this problem.
An ideal backpack should serve several purposes. You went on a mission, the next day you can ride a motorcycle and enjoy the free road. After the hike through the forest is done, you can throw your books and laptop in when you go to school on Monday.
